Abū Ismāʿīl al-Ashʿarī al-Kūfī, the jurist, and one of the narrators from Zayd ibn Abī Unaysah, as stated in Tahdhīb al-Mizzī.

Second: al-Haythamī attributed it to al-Ṭabarānī’s al-Awsaṭ, but not to his al-Muʿjam al-Kabīr; this was an omission, for he also recorded it there—as previously indicated—with its chain of transmission and its text.

We subsequently realized, after documenting the hadith, that it had already been included and printed in the fifth volume of this Silsilah, under no. 2084. There is benefit in repeating it, Allah willing, especially since there is an additional wording here that did not occur there.

With that said, I state:

The Prophet, may Allah bless him and grant him peace, came out to them at midday while they were performing their voluntary prayers seated, and he said...” He then mentioned it.

It was narrated by ʿAbd al-Razzāq in al-Muṣannaf (2/471/4120), from Maʿmar; and Ibn Abī
